3 Terms and Definitions

The following terms and definitions apply to this document.

Maltophilia Aeromonas Stenotrophomonasmaltophilia Maltophilia Aeromonas is a gram-negative bacillus widely distributed in nature, in a wide variety of water, milk, frozen Food, soil, plant roots, animals and humans, is an opportunistic pathogen. Major parasites in the respiratory tract, causing respiratory tract infections, may also lead from endocarditis, septicemia, pneumonia, meningitis, urinary tract infections. The typical biochemical characteristics are. non-fermentative bacteria, no gas, oxidase overcast Nature, DNA-positive, dynamic, esculin hydrolysis, to liquefy gelatin, reduction of nitrate to nitrite. In addition, maltophilia Aeromonas it has a natural resistance to imipenem.
